Macs can’t really make direct use of a U2 PCIe SSD, but maybe a new Apple M2 Mac Pro will offer some bays.
A U.2 SSD is a standardized form factor that slots into a U.2 interface. The enclosure contains an SSD (in theory custom solutions could contain several banks of SSD storage). At present, enclosures like the OWC U2 ShuttleOne allow installation of a single NVMe M.2 SSD into the enclosure. The encosure can then be swapped easily between computers, multiple enclosures can go into computers or other devices with U.2 bays.
This innovative “build your own” heat dissipating full metal adapter brings U.2 SSD performance and capacity to the mainstream in a flexible, easy-to-use design. Performance enthusiasts, IT admins, M&E pros, gamers, and more can now use a readily available and affordable NVMe M.2 “blade” style SSD in a 2.5-inch U.2 bay. Whether you have a U.2 bay equipped server, workstation, gaming rig, or external drive, the OWC U2 ShuttleOne gives you access to a new world of storage possibilities.
The OWC U2 ShuttleOne offers a full-metal housing that solidly protects your drive and data while providing cooling that’s superior to adapters made with other materials. The OWC U2 ShuttleOne delivers complete drive reliability and takes your workflow beyond the limits. Small form factor NVMe M.2 SSDs can pack a powerful performance but swapping them can damage the connector and make the drive unreadable. The OWC U2 ShuttleOne lets you change your NVMe M.2 SSD at will in any 2.5-inch U.2 drive bay with the peace of mind that your drive will stay protected. This innovative adapter is fully certified and rated up to PCIe Gen 4, meaning the OWC U2 ShuttleOne supports your drive’s fastest performance up to 8,000MB/s. The OWC U2 ShuttleOne can make your dream of mind-blowingly fast speeds a reality.
